ESTHER M. MILLER, OF PITTSBURGH, PENNSYLVANIA.

' CUTTING-ALLOWANCE COMPUTER.

Application filed August 6, 1920. Serial No. 401,672.

To @ZZ whom it may concern:

Be it known that I, ESTHER M. MILLEr, a vcitizen of the United States, residing at Pittsburgh, in theA county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Cutting-Allowance Computers, of which improvement the followingis a specification.

My invention relates to shoe cutting allow` ance computer method or system and means for calculating and ascertaining the cutting; allowance given shoe cutters on all material from which a given number of shoes of varying and increasing sizes are to be produced, over a fixed and determined quantity required in the production of an equal number of shoes of a basic or foundation size. In the manufacture of shoes of varying sizes and widths, lallowances in material over and above that amount of material required to produce a'pair of Some basic or foundation size,fusually, in mens sizes, No. 4, is based not only onk differences in size, but also upon differences .in kind and grade of material used, asdifferent kinds and grades of material require different allowances. The ob ject of the present invention is to produce an efficient and readily applied means for ascertainingwith substantial accuracy the al-k lowance given shoe cutters on all kinds and .Grades of material from which a given numberof-pairs of shoes of varying and increasing sizes are to be produced.

I yaccomplish this object by means of the method and appliance which I call a shoe cuttingr allowance computer, which includes a book, a file and a size run or key card and themethod of vusing the same, hereinafter more specifically described, reference being had to the accompanying drawings, forming partA hereof, in which- Fig. 1 is a plan view of a shop card.

1 Fig. 2 is a plan view of the size run or key card.

Fig. 3 is a plan view of one of the pages or lates of the file, being page 2 thereof.

ig. 4 is a fragmentary portion of one page of the book, being page 2 thereof.

Fig.L 5 is a fragmentary portion of page 11l of the book. e

Referring to said drawings, A is abook two pages vof which is shown and contains the data from lwhich the various patterns arebuilt or roduced; that is, it shows or contains'xec 'data of a certain givensized Specification of Letters Patent.

pattern, i. e., the smallest size manufactured, and comprehends or includes the use of dii ferent kinds and grades of material, ranging in quantity from one one-hundredth (.01) of a foot up to five feet, in the production of pairs of shoes of varying widths and from one pair to one hundred pairs, and consists of a number of pages, numbered from 1 to 42 inclusive, on each of which are inscribed twelve columns of figures. Y The marginal column, 1, running in consecutive order from 1 to 100, indicates the number of pairs, and the intermediate or succeeding columns, 2, 3, 4, 6, 7, 8, 9, 10, 11, 12, 13, indicate the amount or quantity of material from one one-hundredth (.01) of a foot up to tive (5) feet, required in the fabrication of from one pair to one hundred pairs of shoes, of varyingv widths or patterns manufactured, the initial figure or iigures of each column increasing overk the initial figure or figures of the preceding column by .01 throughout the book, so that each page increases over the preceding page 0.12 of a foot.

B is the file, one page of which is shown andv contains data showing a key number, which is the exponent of increase in quantity of material in sizes and half sizes, starting and increasing from the smallest size to the largest size manufactured, showing also the increase. The said tile consists of a number of plates or cards, 11i, numbered consecutively from 1 to 10, on each of which is indicated or inscribed a series of columns of figures, the columns, 15, running in consecutive order from 1 to 500 and arranged Y preferably in divisions or sections, each containing one hundred numbers, and indicate the iile number` which is the exponent of the allowance on any specific factory card or order above the amount of material required in the yconstruction of an equivalent number of pairs of shoes of the basic or smallest size manufactured. The intermediate columns, 16, or the columns immediately tothe right of said consecutive columns, indicate in figures and decimals thereof the increase or'variation in amount of material between sizes and half sizes in the different kinds and grades of material over and above the basic size. p

The size run card, C, is a card havingr a series of rows of figures, 1G. T he lowerniostrow, running in consecutive order from zeror up to 17, indicates the number of sizes and half sizes from and between the smallest or basic size up to the largest size.

In the application of this key card to ascertain or determine the allowance on any given order indicated on a shop or factory card, X, the key card is applied to the factory card, on which is inscribed the number ofpairs of shoes to be made, the sizes and the'kind of material and grade thereof, arranged in columns similar to those on theI key card. The shop card has also a pattern number on the margin thereof. The size run card is applied to the factory card, so that the basic column represented by the cipher on said card will be in direct alignment and immediately above the smallest size shoeindicated on the factory card. A The figures in the lowermost row on the size run card are then multiplied by the figures immediately below them on the factory card, and the aggregate of said figures found by adding the same together is the number in the file which indicates or is the exponent of the allowance on the specific order on the shop card, over the same number of pairs of the basic size, i. e., No. 4. The operator then ascertains the quantity of material required to produce the equivalent number of pairs oflshoes of the basic or smallest size, i. e., No. 4, by referring to the pattern number in' the book and the number of pairs. The ligure so found is added to the allowance ascertained in the file, whichigives the quantity required to vproduce the number of pairs specified on ,the shop or factory card.

As an example, in the drawings is shown a Shop card, X, which calls for eighteen pairs of 'D width shoes, in varying sizes, rangingfrom size 6 to size 11.

The pattern number on the margin of said cardY is 132.

ABy placing the size run card immediately above the line on which the various numbers of pairs are indicated, we bring the column on the size run card over the column fl on theV Shop card. We then find that we have immediately above the first single pair ordered,the figure, which we put in a column. vThe next we have, one single pair and above 1 the figure', nexta-two pairs and above that 6. rI wo times six is twelve; two

times seven, fourteen;two times eight, sixteen; two times nine, eighteen; two times ten, twenty; two times eleven, twenty-two; two times twelve, twenty-four; one pair of No. 13 and one pair of No. 14; which figures added together produce the le number 162,

` which is the exponent Vof the allowance sought, and upon reference to the file, weV find that 162 is the exponent or key number for 3.24`feet of material, i. e., the amount of `material in excess of the amount required to make eighteen pairs ofV No. 4 shoes. By then referring to the book, we find `that widthv D, eighteen pairs ofV No. 4 size shoes,

requires 23.7 6 feet of material, which added to the allowance due to the variation in the order from No. e, i. e., 3.24: feet, gives -27 feet, being the amount of material required to produce the specific order set forth on the shop card.

Having described my invention, what I Aclaim and desire to secure-Letters Patent J: T, iS Y 1. A shoe cutting allowance computer for calculating and ascertaining the quantity of material required in the manufacture of shoes (if-varying sizes and widths, which includes a book having tables showing the amount of material in feet and fractions rof a foot required to make pairs of basic size shoes of varying widths fabricated from material of different kinds and grades, a le` having tables and key numbers thereto, showing the increase in quantity or allowances of material required in the manufacturingY of shoes of increasing sizes and half sizes above said basic size, a shop card showing the number of pairs of varying sizes to be made and varying kinds and grades of material, and.

means applied to said shop card for ascertaining the key number corresponding with the allowance of material required above the basicV size in the production of the specific order set forth in said shop card.

2. A shoe cutting allowance computerfforV calculating and ascertaining allowances in material in the manufacture of-shoes ofvarying sizes and widths, which includes a book, comprising series of pages, each page provided with series of columns ofV figures, i
